JAMES F. LEARY; OF ROCHESTER. NEW YORK.

CLEANER FOR WIND-SHIELDS.

Application filed December 29, 1915.

To all whom it may concern:

Be it known that 1, JAMES F. LnAnr, citizen of the United States, residing at Rochester," in the county of Monroe and State of New York, have invented certain new and useful Improvements in Cleaners for Wind-Shields, of which the following is a specification.

The object of this invention is to provide a new and improved form of cleaner for Windshields, or an apparatus by which the snow or drops of rain may be removed from the glass of the windshield repeatedly during storms as fast as they accumulate thereon and while the car is running. This and other objects of the invention will be fully illustrated in the drawings, described in the specification and pointed out in the, claims at the end thereof.

In the drawings, Figure 1 is a front eleva tion of my improved windshield. Fig.' 2 is a horizontal section on the line 2 -2" ofv "Fig. 1. Fig. isa horizontal section on the 'line'3"3" of Fig. 1. Fig. 4 is a vertical section on the line 4 4 of Fig. 3. Fig. 5

is a vertical section on the line 5 5 of Fig. 1. Fig. 6 is a vertical section on the line 6"- "hf Fig. 1. Fig. 7 side elevation of the cam in the frame for controlling the movement of the windshield cleaner. Fi 8 is a perspective detail view of the me or. arm which is used in each end of the cleaner to coiiperate with'the cams in the frame. Fig. 9 is a perspective view of the rocker arm viewed from the side opposite that shown in Fig-'8. Fig. 10 is a detail perspective view of'the upper portion of one of the sliding. mounts that carries the .windshield cleaner. Fig. 11 is a perspective view of a portion of the cleaner itself.

I, In the accompanying drawings like referonce numerals indicate like parts.

' Inthe drawings reference numeral 1 1ndicates the frame by which the glass of the windshield is supported and 2 indicates the :glass of the windshield, it being understood that the glass is preferably in a single piece *thatgextends continuously from the top to the bottom of the frame; The upright sides of -this frame indicated by reference numerals 3 and a]. are grooved at 5 and 6 to hold the glass and are grooved at 7 to hold the sliding mount for thev cleaner. nd its rocker arm and-are groo-ved' at Sand 18 to v a with the pins on the roclre'r arm by who: the cleaner rubber is osc llated Specification of Letters ram.

held in a retracted position during its upward movement and held in its normal POSi-E t1on during its downward movement.

Reference numeral 9 indicates the support or backing for the cleaner or rubber and 10 indicates the rubber strip carried thereon by which contact is made with the glass for the purpose of'wipi'ng the glass. On each end of the support is attached "a rocker arm 11 by which the oscillation of the support and rubber is controlled. This rocker arm has a pin 12 thereon which engages with the cylindrical piece 13 thereon on which are carried the pins 14 and 15. The cylindrical piece 13 is cut away to leave asegmental shoulder 16 substantially a quadrant .in

shape. The pin 12 of the rocker arx'n engages with the sliding mount 17 and travelsup and down with it. This sliding mount 17 engages with the large groove 7 formed on each side of the frame which groove extends from the top to the bottom thereof.

The large groove. 7 is a wide shallow groove and has extending therefrom at the upper end thereof the narrow grooves 8 and '18, the groove 8 running straight and par- Patented Dec. 19, 1916.

allel to the glass and the groove 18 lying I \Vhen the wiper is at the top of the frame I the pins 14 and 15 will both be-in engage- -ment with the groove 8 and will'remain 1n engagement therewith as the wiper with the slides 17 travel down until the pin 15 passes the end of the groove 18. At the-end of the.

groove 18 and normally separating it from the groove 8 is a flat spring 19 past which the pin-J-Y-readily travels. Thisspring will snap "in behind the pin15 and as the wiper travels up carrying with it the .rocker arm the pin 15 will pass into the cam groove 18 and will travel upwardly therein causing the rocker arm to rock from the position marked IV in Fig. 7 in whichposition the "wiper will be held withdrawn from the glass as is indicated in Fig.2; Asthewiper moves up it will be held inthis position until it reaches the top ofgthe cam slot, 1?, when it wilLbe rocked to. the position ifldl-r v cated by I in .Fig. 7.', At the. top of the groove 8 is a flat spring Z Q'yhich the-pin 15. can readilypass hind thelp n and 33 are connected to the latches 39 car- .ri ed 0n the slides 17 which latches are piv i the frame by 18 compelling it when it moves down in the reverse direction to follow the slot 8. This causes the rocker arm and rocker to swing and bring the wiper forward in contact with the glass, the position of the parts at the top of the glass being shown in Fig. 5. It will be understood that the sides of the frame 3 and 4: are duplicates of each other except that theposition of the parts therein are reversed from right to left as will be necessary owing to the fact that the sides set opposite to and facing each other so that the rocker arm, sliding mount, large and small grooves that have been heretofore described in connection with the side 4 are equally present in the same construction and operation in the side At the top of each of the sides are mounted. pulleys and 26. Connected to the slides 7 and 8 at the top are ropes 27 and 28' which pass up over the pulleys and down through the sides of the case and are attached. to springs 29 and 30 located at the bottom of the sides. These springs normally draw down on the ropes and are for the purpose of holding the wiper normally at the top of the glass.

At the bottom the slides 17 are connected by the cross bar 31, the cross bar, the wiper and two connecting slides constituting a frame of sufficient rigidity. Connected to the bottom of the slides are the ropes 32 and 33 which pass around pulleys 3d and 35 and extendtoward each other in. the bot tom of the frame, passing around pulleys 36 l and 37 and extending out below the frame at 38, the ropes being connected to a ring below which the wiper may be read 11y drawn down by hand or they may be connected to a treadle by which the Wiper may be drawn down instead. The ropes 32 ot'ed and are pushed sidewise against the when it is hld in y The operation of my device is as follows:-

the position shown inEig.

'frame by the springs 40, the springs pushing the slide in one direction and the latches in the other-dimction'thus taking up the lost motion that may exist between the frame and the slide.

In order to compel the wiper to rotate in the right direction and the correct distance,

the segmental shoulder 16 is provided, which shoulder engageswith the shoulder 41 provided on the slide 17 by of the windshield is recessed ch42 to receive the support 19 for its raised'position.

With the wiper in said slides, a

said cleaning which its movement I to the right or left is limited, the rocker arm on opposite sides" mounted to swing on on. said cleaning device engaging with said said cleaning device, the wiper and conceal t 5 at the top the operator pulls on the handle and draws the wiper down along the glass removing from the glass the rain or snow that would otherwise obstruct his vision and this downward movement of: the wiper continues until the wiper and rocker arm has moved for enough for the pin 15 to pass the spring 15) which guards the opening into the cam slot 18, when the wiper can be released by the OPGZiItOl. and the springs 29 and 30 will then operate to draw the wiper up. The pin 15 on each end of the wiper will be deflected by the spring 19 into the cam slot 1.8 and will cause the wiper to rock away from the glass and hold it aw'ayii'oni the glass until the wiper has traveled to they top of the slots 8 and 18 after which the pin 15 will pass through the slot 18 and into the slot 8 and rcsti'u'e the wiper to its normal position shown in. Fig. 5. The spring will then close in heel; of the pin 15, closing the slot 18 and forcing it to travel in the slot 8.
